Antibiotics and CBD Oil: Safe to Take Together?

CBD oil and antibiotics both have germ-killing abilities. But should you take them together?

With new health benefits constantly being discovered, CBD oil has been one of the most exciting medical developments of this century. But almost 100 years before cannabidiol came into the spotlight, antibiotics completely revolutionized medicine and have held their place as a staple of healthcare since.

Together, could this combination be a powerful dream team? Or a match made in hell?

People around the world take CBD oil for a range of conditions; whether for sleep, mood, muscle repair, pain relief, or inflammation control, it can become an important part of your daily routine. Understandably then, if you are told you need to take antibiotics, you’ll want to know whether you can continue to use CBD oil.

Understanding the potential advantages and disadvantages of using CBD oil in conjunction with antibiotics will help you to make an informed decision on how best to carry out your treatment. But as always, this article serves only to educate and should not be substituted for medical advice. Always consult your doctor before using CBD oil with antibiotics.

CBD Oil and Antibiotic Interaction

CBD oil is widely considered to be a safe product that is well tolerated by the majority of people and carries a low risk for side effects. However, when combined with certain pharmaceutical medications, care must be taken. This is due to the relationship between CBD oil and the cytochrome P-450 enzyme system.

Located in the liver, the P-450 system contains more than 50 enzymes that help your body break down toxins. Many common medications are processed through this system, though common antibiotics like penicillins are actually inhibitors of this system as well. The only antibiotics processed by the P-450 system are clarithromycin (Biaxin) and erythromycin.

If you’re taking either of these antibiotics, CBD oil could slow down the time it takes your body to process them in what is referred to as the ‘grapefruit effect.’ (Grapefruit also inhibits the P-450 system.) This inhibition increases the amount of time the medication’s active ingredient is present in your system, and can make it more likely that you’ll experience side effects.

Generally speaking, it isn’t necessarily unsafe to take CBD oil and antibiotics together, but it’s important to understand how the combination could affect you. So, talk to your doctor before you begin using CBD oil and antibiotics together. You can also consult a naturopathic doctor who specializes in using cannabidiol to treat certain medical conditions.

Effectiveness of Using CBD Oil and Antibiotics Together

CBD oil and antibiotics both fight infection, but they don’t do it in the same manner.

While different types of antibiotics vary in their method of fighting infection, they all have a general function: targeting the elements of bacterial cells that aren’t present in human cells. This is an incredibly thorough method of fighting infection; it wipes the slate clean, so to speak, destroying all bacteria in the body, even the good bacteria (probiotics) that keep your gut healthy. Your medication will also exclude any bacteria that have become resistant to antibiotics.

CBD oil has been shown to have antimicrobial properties, making it another tool for fighting infection. While we don’t yet understand how CBD oil fights bacteria, studies have confirmed that this is the case, and that it is particularly useful in attacking bacteria that have become resistant to traditional antibiotics.

One such study investigated how various cannabinoids, including CBD and tetrahydrocannabinol (THC), affect pathogenic bacteria. Each cannabinoid was tested against six strains of the antibiotic-resistant superbug MRSA. All of the cannabinoids showed “potent activity” against the bacterium, with researchers noting that “activity was exceptional against some of these strains, in particular, the multidrug-resistant (MDR) SA-1199B” and also “against EMRSA-15 and EMRSA-16, the major epidemic methicillin-resistant S. aureus strains occurring in U.K. hospitals.” In other words, cannabidiol was proven to be effective at fighting one of the most treatment-resistant strains of bacteria medicine has seen.

If you can get the dosages right, using CBD oil with antibiotics can offer a powerful, two-pronged approach to fighting bacteria-generated illnesses. Or, after consulting your doctor, you may choose to try using a high-concentration CBD product on its own to fight infection at first. This will preserve the good bacteria in your body and may help reduce the growing number of treatment-resistant bacteria in the world today, which come as a result of unnecessary and incorrect usage of antibiotics.

Side Effects of Using CBD Oil with Antibiotics

As mentioned above, CBD oil may slow down your ability to metabolize clarithromycin (Biaxin) and erythromycin. It’s important to note here that these two antibiotics can be prescribed on their own and may also be included in medications that contain a mixture of antibiotics. This is why it’s important you read your labels and consult your physician.

Since CBD slows the breakdown of these antibiotics, your chances of experiencing their side effects could increase.

If combining CBD oil and clarithromycin, you might be more likely to experience side effects like:

Nausea

Diarrhea

Headaches

Mood changes

Weakness

Stomach Pain

If combining CBD oil and erythromycin, you could have a higher chance of experiencing side effects like:

Nausea

Diarrhea

Stomach pain

Liver disease

Muscle weakness

CBD Oil for Side Effects of Antibiotics

Antibiotics have saved hundreds of millions of lives since penicillin was first discovered in 1928, but they come with some side effects, too.

Until CBD oil’s antimicrobial effects are better understood, its greatest use in combination with antibiotics may be mitigating their side effects.

Generic Name

Common Side Effects

CBD Oil

Amoxicillin

Nausea; vomiting; stomach pain

Combats nausea and vomiting and reduces the experience of pain

Azithromycin

Nausea; vomiting; stomach pain

Combats nausea and vomiting and reduces the experience of pain

Clindamycin

Nausea; vomiting; joint pain

Combats nausea and vomiting and reduces the experience of joint pain associated with conditions like rheumatoid arthritis

Cephalexin

Nausea; vomiting; stomach pain

Combats nausea and vomiting and reduces the experience of pain

Because CBD oil has properties that counter the most common side effects of antibiotics, many people report that when combining the two, they don’t experience any side effects at all. While this is only anecdotal, it is certainly worth considering.

Best CBD Oils to Use with Antibiotics

If you are using CBD oil and need to take a course of antibiotics, speak to a medical professional to discuss the best way forward. Once you have the thumbs-up from your physician, it’s time to choose your CBD product!

To make sure you’re shopping with high-quality CBD oils brands, look for third-party lab testing and Certificates of Analysis. Certificates of Analysis give you the chance to see exactly what is in your CBD product, especially in the way of potency and safety. Finding an organic CBD product will further ensure you’re getting premium CBD oil without any dangerous pesticides or herbicides.

You may also want to think about the method you’ll use to take CBD. If, for example, you have a chest infection, you may feel more comfortable taking your CBD oil in capsule form as opposed to using a vape pen. Explore what your CBD brand of choice has to offer, and reach out to them for the most accurate information about how long it will take the effects to set in, and how long they will last for.

CBD Oil Dosage

Because the amount of CBD oil required to show effects depends on a number of factors like your metabolism, age, and weight, there is no one dose that can be applied across the board.

It’s best to start with the lowest recommended amount that appears on your product. From there, the dose can be adjusted up or down as needed. With no significant side effects, no intoxicating effects, and no risk for overdose or addiction, you confidently experiment with dosage and concentration until you find what works best for you.
